Based on the last Pic, S1 and S2 cannot have the same CSA.
It's really tough to model a 5 section horn path in HR with only 4 segments. You should use Vtc/Atc as S1-S2 and S2-S3.

BP,
i am just RE- POSTING what i recollected on the FT30 thread about a non cone corrected plan of the FT 30
this variation was done by XOC1 based on his TH18
what are you saying about
buy if you can correct or fix the HR model
i am more than happy to see it done !
this was the original PIC

Is there a cutlist? J/K
Just want to say thinks for reviving this design. Always liked it and wondered why it got no love.

no cut list... but you can use
https://www.cutlistoptimizer.com/
thats what i use to calculate the cut list and minimize the wasted ply
and is easy to do , you are in the USA so the inches model will fit
you need to print... the plan... name all the panels...
and input in the webpage i shared with you
since we know the INTERNAL WIDTH of the cab is 588mm that is 23 1/8″
so the front is
23" 3/16 x 23" 1/8
i made the 1st panel for you
then you keep going with the rest if the internal panels
( panel measurement in the plan ) x ( width)
( panel measurmenet in the plan ) x 23" 1/8"
all the internal panels have the internal width
just the TOP , BOTTOM and BACK panels will change
as the external width that take in account the 18mm or 3/4"
hope this helps

Based on that pic,
S1, S2, and S3 should all have a CSA of 532.73cm2.
L23 should be 27.24cm.
L34 should be 208.05cm + 98.93cm - 27.24cm.
Constant parabolic positive or negative flare horn paths cannot be broken into 5 sections and still have a square or rectangular enclosure.
Hence, single fold (2 sections) or double fold (4 sections) TH's.
The Keystone TH does not have a constant parabolic positive flare horn path. 1 of the 3 sections has to be adjusted to square up the enclosure. The easiest way to do so is to have 1 section a straight flare.
That pic starts with a straight flare section from S1 to S3. S3 to S5 is double fold TH.
I'm not sure , what for sure is the FT30..crescendo made 4 I think, and he loves them, I have the CNC files for the FT30's if you want them and have access to a CNC shop
The plans along with the bracing for 4 FT30's
The driver for it is the B&C 18SW115
Idk if some less capable driver can survive the cabinet.

Ah it’d be a DIY non-CNC build for me, do the plans you have have come correction for the 18sw115?
If so would you be able to share them with me.

Sure , let me get back to my PC on Tuesday after labor day holiday 🤠
The files are on this thread but can't remember what post#
If you wait, you will save the hassle of dig trough it all!! Fiuuuuuu!!

that's the monsters right there
the chair was used as size reference

Maybe , people don't like too much folding? Or too much plywood? Or too expensive driver?
Combination of those or all of them?
Idk but the few who built them and post their feat, love em!
Also in post #773 - the box is 61cm wide external dimension!
I know it's been over five years since you posted this spacer ring Justin, did you like the 21's in these or find it wasnt necessary?
I acquired an 18LW1400-8 for a great price, very keen to build one of these boxes! This 18Sound driver sims nearly identical to the B&C 18TBW100-8.

This is what i have been looking for! does any per chance have the CNC files? plan to load it with B&C 18TBX100 to start a home mini rig. thanks!
